HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 770, 59 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 770, 59 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 453, 770, 59 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 453, 770, 59 is 1.
HCF(453, 770, 59) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 453, 770, 59 is 1.
Step 1: Since 770 > 453, we apply the division lemma to 770 and 453, to get
770 = 453 x 1 + 317
Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 317 and 453, to get
453 = 317 x 1 + 136
Step 3: We consider the new divisor 317 and the new remainder 136, and apply the division lemma to get
317 = 136 x 2 + 45
We consider the new divisor 136 and the new remainder 45,and apply the division lemma to get
136 = 45 x 3 + 1
We consider the new divisor 45 and the new remainder 1,and apply the division lemma to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 453 and 770 is 1
Notice that 1 = HCF(45,1) = HCF(136,45) = HCF(317,136) = HCF(453,317) = HCF(770,453) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 1, we apply the division lemma to 59 and 1, to get
59 = 1 x 59 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 59 is 1
Notice that 1 = HCF(59,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 453, 770, 59?
Answer: HCF of 453, 770, 59 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 453, 770, 59 using Euclid's Algorithm?
Answer: For arbitrary numbers 453, 770, 59 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
